SHORT TERM /THROUGH TONIGHT/

Issued at 116 PM CST Fri Nov 21 2025

Rain will come to an end tonight as the wave moves east of the area. Drier air, denoted in the GFS bufr soundings along with DVN 18Z RAOB, will keep this rain south, even though radar depicts returns as far north as I-80. Expect a more pronounced trend toward clearing skies overnight as lows dip into the 30s.

Saturday, ridging and high pressure builds into the area. This will usher in a quiet and highly favorable start to the weekend with mostly sunny skies. The pleasant forecast is accompanied by a warming trend, with afternoon temperatures climbing into the mid 50s, above normal for this time of year. Ensemble guidance is in excellent agreement on overall pleasant temperature pattern, with a majority of solutions tightly clustering tightly between 52 and 57 degrees. Main theme, be sure to get out and enjoy the weekend weather!

LONG TERM /SATURDAY THROUGH FRIDAY/

Issued at 116 PM CST Fri Nov 21 2025

Overall, long term discussion from overnight is still representative.

Sunday...While a Rex Block reigns acrs the western third or so of the CONUS, the local area will be the beneficiary of lee side ridging and southerly return flow making for a dry and mild weekend for late November. As long as we get the sunshine, advected in thermal parameters support highs in the 50s and diurnal swing lows in the low to mid 30s Sunday morning. Sunday we could have some 60s in several locations. South winds and increasing high cloud cover will make for milder lows by Monday morning.

Monday through Thursday...The latest suite of ensembles suggest the upstream undercutting low pressure portion of the block out west will look to roll toward the area by Monday night. Pre-wave warm moist conveyor will look to fuel rain moving up acrs the area by Monday afternoon and lasting well into Monday night, then moving off to the east Tuesday morning. Early indications this may be another tenth to near a half inch rainfall event. The mild temps look to continue through at least Tuesday, then beyond in the mid to late week period, it appears wavy with a lot of noise in the ensembles making for low confidence at this juncture. Flow patterns and mid CONUS baroclinic lay out at question and showing high variance, but a general cooling trend may look to happen. The steering flow could be split again and making it hard to determine where the prime west- east baroclinic storm highways lay out acrs the central CONUS. Of course this leads into a high profile holiday period late week and a window to watch for trends of potential rain or snow makers.

AVIATION /00Z TAFS THROUGH 00Z SATURDAY/

Issued at 511 PM CST Fri Nov 21 2025

Rain across southeast Iowa and Illinois will end by 06z/22 as the system moves into the Ohio Valley.
